Multiple integer overflows in libgd in PHP before 5.2.4 allow
remote attackers to cause a denial of service (application crash)
and possibly execute arbitrary code via a large (1) srcW or (2)
srcH value to the (a) gdImageCopyResized function, or a large (3) sy
(height) or (4) sx (width) value to the (b) gdImageCreate or the (c)
gdImageCreateTrueColor function. (CVE-2007-3996)
The updated packages have been patched to prevent this.
